Crossing Over is an exhibition of contemporary art bringing together art, design and biotechnologies. Integrated in the fabric of the Royal Institution building, artworks by eleven artists and designers investigate the metaphors, potentialities and anxieties of genetic manipulation and bioengineering. The catalogue includes essays on the single artworks by Caterina Albano, including Mixing the Context (pp. 6-8) and Art and Biotechnologies (pp. 17-67),and contributions by Sarah Franklin, who considers the development of biotechnologies, and by Richard Ashcroft, who reflects on the ethical implications of biotechnologies and on the role of the visual arts in the debate.
